Embodiment 1

[0055] This embodiment provides a method for automatically disassembling the scrapped and recycled power battery pack of a new energy vehicle, such as figure 1 As shown, the method includes:

[0056] S1. Lift the new energy vehicle and clean the chassis.

[0057] When the power battery pack reaches the scrapping standard or the new energy vehicle reaches the scrapping standard, the power battery pack needs to be disassembled. During the use of new energy vehicles, the chassis of the car will be covered with dust, water, etc. Therefore, it is necessary to clean the chassis of the car when it is automatically disassembled. Manual disassembly does not require high chassis cleanliness, and generally does not require chassis cleaning.

[0058] In this embodiment, firstly, the car is lifted to the top of the cleaning equipment. Then, wash the chassis of the car through a high-pressure water gun, and the pressure of the high-pressure water gun is 10Mpa-25Mpa. Finally, the car cha...

Embodiment 2

[0101] like image 3 As shown, this embodiment provides an automatic disassembly system for scrapping and recycling power battery packs of new energy vehicles, including:

[0102] Lifting and cleaning module 110, used for lifting new energy vehicles and cleaning the chassis;

[0103] The data acquisition module 120 is used to read the structural parameters of the power battery pack stored in the two-dimensional code of the chassis;

[0104] The image acquisition module 130 is used to acquire the image of the automobile chassis, and sends the acquired image to the image processing module;

[0105] The image processing module 140 is used to process the image of the automobile chassis, and recognize the screws in the image;

[0106] A calculation module 150, configured to calculate a virtual distance and a virtual included angle according to the screw information identified by the image processing module;

[0107] Comparison module 160, used to compare virtual parameters and s...

Abstract

The invention provides an automatic disassembling method for a scrapped and recycled power battery pack of a new energy automobile. The method comprises the following steps of lifting the new energy automobile, cleaning a chassis, acquiring structural parameters of the power battery pack, collecting an image of the automobile chassis, identifying screws in the image, calculating virtual parameters of two adjacent screws, and comparing the virtual parameters with actual parameters; and finally, the dismounting device being guided to be close to the dismounting starting point, the screws on the lifting lugs of the power battery pack being sequentially dismounted along the dismounting path, and dismounting of the power battery pack being completed. The invention further provides an automatic dismounting system which comprises a lifting cleaning module, a data acquisition module, an image acquisition module, an image processing module, a calculation module, a comparison module, a dismounting module and the like. According to the automatic dismounting method and system provided by the invention, the power battery pack can be automatically dismounted, dismounting efficiency is improved, and a safety problem in the dismounting process is avoided.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and more specifically, relates to a method and system for automatically disassembling scrapped and recycled power battery packs of new energy vehicles. Background technique [0002] In recent years, with the gradual improvement of infrastructure such as charging stations for new energy vehicles, the scale of the domestic new energy vehicle market will continue to expand. According to statistics, the number of new energy vehicles has exceeded 1 million for three consecutive years, showing a continuous high-speed growth trend. By the end of 2020, the number of new energy vehicles in the country will reach 4.92 million, accounting for 1.75% of the total number of vehicles. According to the calculation of the service life of new energy vehicles, in the next five years, new energy vehicles will usher in the first peak of scrapping and recycling. [0003] There are huge differences in processes, tec...
